6 min: And after all that promise, Newcastle are behind. Raphinha is coolness personified as he slots low past Ramsdale.

Yamal creates it with a wonderful turn on halfway that leaves Thiaw on the ground. He plays a through ball that squirms past Hall and towards Lopez, who then finds captain Raphinha about 14 yards from goal. He takes a touch to steady and then side-foots clinically past Ramsdale, leaving Newcastle’s goalkeeper with no chance.

3 min: Now Newcastle win a corner which Trippier takes. It isn’t great but Barca are also unable to clear properly and, eventually, Burn takes a surprise shot which Garcia does well to save. This an impressive opening from the Premier League side.

2 min: Anthony Gordon buys a smart foul from Eric Garcia after 40 seconds with the Barca right back fortunate not to be booked for a cynical shirt pull. Sandro Tonali lines up the delivery from the left but it is half-cleared to Anthony Elanga, whose return is claimed by Joan Garcia in the home goal.

We are underway on a cloudy evening. Newcastle, playing from right to left as we watch, play it straight back for Aaron Ramsdale to pump down the left flank.

The teams are jogging up the half dozen steps between the tunnel and pitch, they walk under a big blue arch reminding us the final will be in Budapest and emerge to a cacophony of noise.

It does look rather windy going off the flags being waved in the stands.

Speaking to TNT Sports from inside the stadium just now, Howe says: “We performed well a week ago so looking for a similar performance and take a couple more of the chances we got,.

On Barcelona, he adds: “They could slightly tweak things. Both teams are quite consistent in selections. It’ll be how they use the ball in tight situations. We know we have to be at our very best to qualify and that’s what we’ll try to deliver.”

Both sides have four players who are one yellow card away from a one-match ban that would be served in the first leg of next month’s quarter-finals should their team prevail tonight.

Barcelona: Lamine Yamal, Fermin Lopez, Gerard Martin and Marc Casado

Newcastle: Joelinton, Sandro Tonali, Dan Burn and Joe Willock

Lamine Yamal made his European debut more than 900 days ago but this is his first knockout match at Camp Nou, which is still very much under construction with yellow cranes visible behind the stands.

The players are just emerging from the tunnel for their warm-ups, with TNT Sports saying that Newcastle are in a temporary changing room that means quite a long walk to the pitch.

No surprises from those starting XIs as Eric Garcia replaces Ronald Araujo in the home defence while up front for Newcastle, as expected, Anthony Gordon replaces Will Osula. Both of last week’s starters have dropped to the bench.

The Magpies have already been out to inspect the Camp Nou surface, not long after some pigeons landed on the hallowed turf.
